Friedrich MR12C1H Ignition Control Board
An ignition control board oversees the main gas intake valve, the ignition sequence and some other sensors. The ignition control board was always an important circuit board that has now become a standard part of the main board instead of a separate board.
Major symptoms the ignition board will eventually need to be replaced
- HVAC ignition cycle can not kick in even though it is supposed to
- Any other device connected to the system is inspected and turns out to be fine
- The on-signal from the thermostat never turns up at the main board
